feat: refactor config flow and directory structure

- Create config-provider.yml (reusable workflow, conf→JSON)
- Replace duplicated job env blocks with workflow env + fromJson
- Move provider workflows to workflows/ directory
- Move consumer scripts to .gitea/scripts/
- Move feature-env.conf to .gitea/workflows/
- Add bats-report.sh for TAP→HTML conversion
- Update ci.yml with setup→needs→with pattern
- Add ADR 0006 directory ownership
- Document cross-job config propagation in ci-pipeline-practices.md
- Remove config.yaml, scripts/load-config.sh unused

.gitea/workflows/ci-engine.yml
